Activation in mesolimbic and visuospatial neural circuits elicited by smoking cues: evidence from functional magnetic resonance imaging.
(Am J Psychiatry, 2002-06)
OBJECTIVE: The authors sought to increase understanding of the brain mechanisms involved in cigarette addiction by identifying neural substrates modulated by visual smoking cues in nicotine-deprived smokers. METHOD: Event-related ...
Neural correlates of categorical perception in learned vocal communication.
(Nat Neurosci, 2009-02)
The division of continuously variable acoustic signals into discrete perceptual categories is a fundamental feature of vocal communication, including human speech. Despite the importance of categorical perception to learned ...
Dominance, politics, and physiology: voters' testosterone changes on the night of the 2008 United States presidential election.
(PLoS One, 2009-10-21)
BACKGROUND: Political elections are dominance competitions. When men win a dominance competition, their testosterone levels rise or remain stable to resist a circadian decline; and when they lose, their testosterone levels ...
Enhanced rewarding properties of morphine, but not cocaine, in beta(arrestin)-2 knock-out mice.
(J Neurosci, 2003-11-12)
The reinforcing and psychomotor effects of morphine involve opiate stimulation of the dopaminergic system via activation of mu-opioid receptors (muOR). Both mu-opioid and dopamine receptors are members of the G-protein-coupled ...
Functional parcellation of attentional control regions of the brain.
(J Cogn Neurosci, 2004-01)
Recently, a number of investigators have examined the neural loci of psychological processes enabling the control of visual spatial attention using cued-attention paradigms in combination with event-related functional magnetic ...
Resolving response, decision, and strategic control: evidence for a functional topography in dorsomedial prefrontal cortex.
(J Neurosci, 2009-10-21)
The dorsomedial prefrontal cortex (DMPFC) plays a central role in aspects of cognitive control and decision making. Here, we provide evidence for an anterior-to-posterior topography within the DMPFC using tasks that evoke ...
